Easiest one yet. Frozen (or thawed if you had time) chicken breasts with a jar of salsa. A little extra seasoning if you wish. https://www.sparklestosprinkles.com/instant-pot-salsa-chicken/ Shred and use for anything. You can use the same process with bbq sauce instead of salsa or even spaghetti sauce.
Also easy spaghetti and meatballs. Again can start with frozen meatballs. https://iwashyoudry.com/instant-pot-spaghetti-and-meatballs/
